AUTOMOBILE-TIRE PUMP.

Specification of Letters Patent.

Patented May 21, 1918.

Application filed March 8, 1917. Serial No. 153,470.

To all whom it may concern:

Be it known that I, MAJOR A. LANE, a citizen of the United States, residing at Paola, in the county of Miami and State of Kansas, have invented certain new and useful Improvements in Automobile-Tire Pumps, filed March, 8, 1917, Sr. No. 153,470; and do hereby declare the followin to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in a pump designed especially for use in inflating pneumatic tires and consists of a simple and efficient device of this nature comprising various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claim.

My invention is illustrated in the accompanying drawings which, with the letters of reference marked thereon, form a part of this specification and in which:

Figure l is a perspective view showing my device as applied to the running board of an automobile.

Fig, 2 is a central sectional view through the pump.

Fig. 3 is a vertical sectional View, parts being shown in elevation.

Fig. 4 is a detailed View of one side of the frame forming a mounting for the pump.

Reference now being had to the details of the drawings by numerals:

14:, 14 designate the opposite end pieces of a frame adapted to support the cylinders 8 of the pump. Said end pieces being held in engagement with the ends of the cylinders through the medium of the rods 14*. One of said end pieces has transverse slots 20 and at the end of one of said end pieces is a horizontally projecting pintle upon which a pinion 2 is journaled, to which is fastened a handle, which is also journaled upon the pintle. Each end piece has a downwardly and laterally projecting arm 19, as shown clearly in Fig. 4c of the drawings, the space intermediate the arms and ends being adapted to receive the running board of the automobile, as shown in Fig. 1 of the drawings, and 18 designates a set screw mounted in a threaded aperture in said arm and which is adapted to bear against the under surface of the running board to securely hold the device in place.

Journaled in the bracket arms 15, which are fastened to one side of the frame, is a crank shaft 4, to which the pitman 6 is pivotally connected,'through the medium of the bearings 5. To the inner end of each pitman is pivotally connected a piston 7, said pitman having a free movement withing the slots 20, as the piston reciprocates.

An exit tube 11 communicates through a branching pipe with each cylinder and the exit opening in each cylinder communicating with the branching pipe is provided with a valve 9, controlled by a spring 10. 7

By the provision of a pump comprising the features of my invention, the recessed side pieces may be slipped over the edge of the running board and fastened thereto, while the tube from the pump may be connected to the valved inflating openings for the tires, and when the pump is not in use, it may be detached from the running board.

That I claim to be new is:

An air pump for inflating tires of automobiles comprising in combination a frame consisting of transverse end pieces and longitudinal tie rods, cylinders mounted horizontally between the end pieces, arms on the end pieces and transversely spaced therefrom, set screws in said arms for clamping the pump to a running board as a support, a crank shaft mounted in brackets upon one of the end pieces, pistons in the cylinders operatively connected with the crank shaft through slots in the end pieces, a gear wheel on the crank shaft, a driving pinion pivoted on the end of an end piece in operative engagement with said gear wheel and a hand crank for manually operating the pinion to drive the pump.

In testimony whereof, I have set my hand in the presence of two subscribing witnesses.
